REG System allows you to manage Thermal Solar Panels, for loading hot water into a tank.
...
P07: Solar panels maximum temp limit, if TS1 exceeds this value the pump is switched off;
P08: Cooling solar panels function, if TS1 exceeds this value, the pump is switched on until the value of P15 or a temperature of 10°C less than the parameter P09: Cooling tank function is reached. This mechanism allows excess heat to be discharged to the heat exchanger inside the tank.
P09: cooling tank function, which allows the activation of the solar pump if the sensor TS3 is higher than the set value AND AT THE SAME TIME the temperature on the solar panels detected by TS1 sensor is lower than 20°C than TS3. The pump is subsequently switched off when the temperature of TS3 drops below:
a temperature value of 10°C lower than P10: Solar panels minimum temperature;
the difference between TS1 and TS3 temperature, when it is less than 10°C
P10: Solar panels minimum Temperature, below this value the Solar Panel pump remains switched off.
P12: Solar panels Antifreeze temp protection. Below this value the antifreeze protection output is activated.
P15: Max Tem. Solar tanks, above which the pump is switched off (if active).
...
Warning
If P08: Cooling solar panels function has been activated, the tank temperature may exceed the values set by P03: main tank high part max Temperature; in any case, the pump will be deactivated when P15: Max Tem. Solar tanks is reached, which is predominant over other factors and acts as a safety limit for the tank.
